Abstract
The invention discloses a hydraulic cylinder structure, which comprises a shell and a piston, wherein the piston moves relatively in the shell, a gap is kept between the piston and the shell, the shell divides the interior of the shell into three chambers through a sealing ring, a connecting rod penetrates through the sealing ring to be connected to the piston, the shell is respectively provided with a compressed air interface tube, a water connecting tube and an air extraction connecting tube which are communicated with the chambers, and a stop ring is arranged in the chamber where the piston is located and fixed with the shell. The hydraulic cylinder structure provided by the invention has the advantages of simple structure, no pollution to the external environment, no influence on working performance due to vaporization of water, and good lubricity.
Description
Technical field
The present invention relates to the nuclear reactor field of engineering technology, particularly a kind of hydraulic cylinder structure.
Background technique
Traditional hydraulic system generally adopts oil as working medium, the hydraulics development of making medium with oil is quite ripe so far, oil can be realized the piston good lubrication, oil can not cause the cavitation of pump because of vaporization simultaneously, but in practice because the requirement of particular surroundings and resource, in order to prevent that the wet goods medium from polluting working environment, the medium of oil and other non-water does not allow to be used in drive system.And available technology adopting water is as the hydraulic cylinder in the hydraulic driving system of working medium, because water does not have lubricity and vaporization easily, piston can produce bigger friction noise when work, and poor lubricity.
Summary of the invention
The present invention has overcome deficiency of the prior art, provides a kind of simple in structure, and external environment condition is not produced pollution, can not influence service behaviour because of the vaporization of water, and the good hydraulic cylinder structure of lubricity.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of hydraulic cylinder structure comprises shell, piston, piston is relative movement in the enclosure, shell is divided into three chambers by seal ring with its inside, connecting rod passes seal ring and is connected on the piston, the pressurized air mouthpiece, water adapter, the adapter of bleeding that are communicated with each chamber are set respectively on the shell, baffle ring places the chamber at piston place, fixes with shell.
The sealing surface of described piston and baffle ring is taper.
Compared with prior art, the invention has the beneficial effects as follows: this device is by cooperating between piston and the shell, under the effect of three chambers, between the sound parts, allow to reveal water simultaneously, having prevented again that water is leaked in the environment goes, and has also prevented the vaporization of water, has good lubricity.
Description of drawings
Fig. 1 hydraulic cylinder structural representation
1 shell, 2a seal ring, 2b seal ring, 3 pressurized air mouthpieces, 4 bleed chamber, the adapter of 5a water, the adapter of 5b water, 6 baffle rings, 7 pistons, 8 water chamber, 9 connecting rods, 10 bleed adapter, 11 pressurized air chambers
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Hydraulic cylinder mainly is made up of shell 1, piston 7, piston 7 relative movement in shell 1, piston 7 keeps suitable space with shell 1, shell 1 is divided into three chambers by seal ring 2a, 2b with its inside, connecting rod 9 passes seal ring 2a, 2b and is connected on the piston 7, the pressurized air mouthpiece 3, the water that are communicated with each chamber are set respectively on the shell 1 take over 5a, water adapter 5b, bleed and take over 10, baffle ring 6 places the water chamber 8 at piston 7 places, and is fixing with shell 1.The conical seal (contact) face of the conical seal (contact) face of piston 7 and baffle ring 6 closely cooperates, and better reaching does not have the requirement of leakage.
The working principle of this device is as follows:
During device work, working medium water is taken over 5b by water and is squeezed into water chamber 8 under water pump and compressed-air actuated effect, promotes piston 7 to left movement.In the process of piston 7 motions, in order to reduce the friction of piston 7 and shell 1, piston 7 keeps suitable space with shell 1, working medium water in the water chamber 8 can be infiltrated the piston opposite side by the space, the water of piston opposite side takes over 5a by water and pipeline turns back in the low pressure water pot, as standby working medium.In piston 7 movement processes, constantly take over 5b and in chamber 8, carry out the moisturizing operation by water.Piston 7 stops to move when piston 7 moves to baffle ring 6 in the water chamber 8, but in order to keep due thrust, still will keep corresponding pressure in the water chamber 8, and this function is that hydraulic pressure system is taken over 5b by water and constantly realized to water chamber's 8 moisturizings.
In the process of piston 7 work, in order to prevent that better working medium is leaked in the working environment, also prevent the liquid contamination working medium in the working environment, in shell 1, its inside is divided into three chambers, in order to isolate the recovery operation medium by seal ring 2a, 2b.Pumped vacuum systems is taken over 10 water that will bleed in the chamber 4 and is extracted out by bleeding, in pressurized air chamber 11, blast the pressurized air of certain pressure simultaneously by pressurized air mouthpiece 3, make the pressure of air pressure, enter hydraulic cylinder to prevent the liquid in the external environment condition a little more than liquid in the external environment condition.Pressurized air chamber 11 is leaked to the air in the chamber 4 of bleeding, and together discharges with water.
When piston 7 needs reversing motion, take over 5a by water and squeeze into high pressure water to water chamber 8, promote piston 7 and move right, take over 5b by water and realize refluxing, in whole process, working medium water is in confined state always, can not produce the vaporization of water.
Piston 7 adopts conical surface seal with baffle ring 6, when piston 7 ran to the left part, the conical seal (contact) face of the conical seal (contact) face of piston 7 and baffle ring 6 closely cooperated, and reaching does not have the requirement of leakage, can realize the long-time stable of ouput force, guarantee that mechanism satisfies force request.
In entire work process, do not have working medium water and be leaked in the surrounding medium and go, do not have environmental liquids yet and bleed in working medium, guaranteed pollution-free generation in the working procedure.
